BRAINCASESkulls have been a part of jewellery design for hundreds of years. The Braincase design is Bobby's interpretation of a classic. These Bobby White Braincase necklaces are made in house at his London workshop by hand using either 18ct yellow, red gold or platinum. The diamonds are D F colour with VVS clarity. The chain runs though the pendant, so a loop doesnt distract from the design. Pendant Measurement 13. 6mm High X 8. 9mm Wide. Chain Measurements
